When i start Forge in my minecraft launcher it goes well at first but then after a while when it starts it just shuts down and says " It looks like you are using an unsupported modified version of the game" and "The game crashed whilst initializing game" and it just won't work. I have checked so that i have uptdate 1.12.2 on forge,minecraft and all the mods (4) i downloaded so i don't know what could be wrong! Here is the error thingy:  Error: java.lang.NoClassDefFoundError: com/mia/craftstudio/IPackReaderCallback

Do you have DecoCraft2 installed? And do you have PTRLib installed with it?

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

what is PTRLib?

It's a library which is required to be installed for DecoCraft to run. Try installing it, a quick search online revealed the same issue with PTRLib missing.

    • As stated in the Title, I can't download forge for minecraft 1.20.06. When I click on the install button i get the AD wall, but after 10 seconds i don't get the red button to install forge.  I also don't see any ads on the site. Does anybode know what to do?  
    • I want to download Forge 1.20.6, but when I press download, it redirects me to Adfocus and does not provide any download. I have never encountered such a problem when I downloaded Forge 1.18.2 at least 12 months ago.
    • did you find any solutions? i have the same problem and also that mahito doesnt transform
    • Here's a simple example to solve this particular issue: public class ModArmorMaterials { public static final DeferredRegister<ArmorMaterial> ARMORS = DeferredRegister.create(Registries.ARMOR_MATERIAL, MyModName.MOD_ID); public static final RegistryObject<ArmorMaterial> COPPER = registerArmor("copper", Util.make(new EnumMap<>(ArmorItem.Type.class), enumMap -> { enumMap.put(ArmorItem.Type.BOOTS, 1); enumMap.put(ArmorItem.Type.LEGGINGS, 4); enumMap.put(ArmorItem.Type.CHESTPLATE, 5); enumMap.put(ArmorItem.Type.HELMET, 2); enumMap.put(ArmorItem.Type.BODY, 4); }), 12, SoundEvents.ARMOR_EQUIP_IRON, 0.0F, 0.0F, () -> Ingredient.of(Items.COPPER_INGOT)); private static RegistryObject<ArmorMaterial> registerArmor(String pGroup, EnumMap<ArmorItem.Type, Integer> pEnumMap, int pEnchantmentValue, Holder<SoundEvent> pEquipSound, float pToughness, float pKnockbackResistance, Supplier<Ingredient> pRepairIngredient) { List<ArmorMaterial.Layer> pLayerList = List.of(new ArmorMaterial.Layer(new ResourceLocation(pGroup))); return registerArmor(pGroup, pEnumMap, pEnchantmentValue, pEquipSound, pToughness, pKnockbackResistance, pRepairIngredient, pLayerList); } private static RegistryObject<ArmorMaterial> registerArmor( String pGroup, EnumMap<ArmorItem.Type, Integer> pEnumMap, int pEnchantmentValue, Holder<SoundEvent> pEquipSound, float pToughness, float pKnockbackResistance, Supplier<Ingredient> pRepairIngredient, List<ArmorMaterial.Layer> pLayerList) { return ARMORS.register(pGroup, () -> new ArmorMaterial(pEnumMap, pEnchantmentValue, pEquipSound, pRepairIngredient, pLayerList, pToughness, pKnockbackResistance)); } public static void register(IEventBus eventBus) { ARMORS.register(eventBus); } } Essentially, the TierSortingRegistry has been removed and so you now need to set up your own DeferredRegister. Please see the minecraftforge GitHub for more information; I found this solution through their issues (https://github.com/MinecraftForge/MinecraftForge/issues/9961)
